Admin Restrict Branch

Recommended Posts

Hi everyone,

Some critical updates this morning:

1) The module stopped doing anything in recent versions of PW 3 - I don't exactly when, but this is now fixed.

2) I also added support for restricting the new Pages > Tree dropdown menu that was added in 3.0.55

Please let me know if you find any problems with these changes or if you find any other situations where the module is no longer working. Given the rapid development of new ways to access the page tree that are being added to PW, I strongly recommend thoroughly testing your site if this module is protecting critical info from certain users. Hopefully everything is already taken care of for the current PW dev version, but with the UiKit admin theme, there could be possible breaks.

Thanks for testing and letting me know!

@adrian Is it possible with this module to hide specific pages under home or I should stay with the hardcoded HideOtherUserPages module?

This module is for restricting users to a single branch of the page tree rather than hiding various ones throughout the entire tree. You'll need one of those other options for that. Maybe a module could be put together with more flexibility, but there are lots more issues when hiding specific pages.

I selected Specified Branch Parent and then on the user's profile field I selected the Home branch. Then on the Branch edit exclusions I selected a page under the Home that I want to hide but it's still visible. What am I missing?

Sorry, I think you have misunderstood how this works. If you are using the "Specified Branch Parent" - that is where you select the branch that you want the user restricted to. The "Branch Edit Exclusions" are just for things like external PageTable branches etc that the user still needs edit access to, even though they are outside their restricted branch.

Does that clear things up?

Ok now I understand, thanks. I will stay then with the hardcoded HideOtherUserPages module.

I am working on a multisite project using single database. I forked multisite.module by Antti and another fork by Soma and started to adapt it for my needs. Luckily I found your module. I tried it out and it fits 90% to my needs and already saved a lot of work. Thanks for this great module. :rolleyes:

To get it working properly I need to make some changes. I think these changes could also be an enhancement of your module and you maybe want to take it.

First of all I need an option to set  branchRootParentId via hook which is currently not possible since the related function isn't hookable and private too.
It would be nice if you could change the visibility of the function getBranchRootParentId() to protected and make it hookable.
As far I can see there is no reason (security) to refrain from this.

Furthermore there are 2 unexpected behaviours or potential issues:

  1. In Processwire the breadcrumb 'Pages' is prepended to breadcrumbs in the PageEdit area of the root page only. @see ProcessPageEdit::setupBreadcrumbs()
    This behaviour is different in your module. The breadcrumb is prepended in any Editor not only for the branchRootParent since $this->wire('breadcrumbs')->count() returns always 0. Is this wanted like that?
    I would prefer the default behavior here. I found a working solution. If you like I could post an issue on github.
     
  2. The BranchRootParent is not prepended to the Pagetree under PagesTab.
    ProcessPageList::executeNavJSON() doesn't prepend branchRootParent here. This couldn't be solved inside your module.
    I can see a PW issue here. ProcessPageList::executeNavJSON() should use $config->rootPageID instead of hardcoded 1

    Possible Solution
    // in ProcessPageList::executeNavJSON
    // Line 489 from
    if(!$parentID) $parentID = 1;
    // to 
    if(!$parentID) $parentID = $config->rootPageID;
    
    // Line 494 from
    if($parentID === 1 && $parentViewable) $items->prepend($parent);
    // to
    if($parentID === $config->rootPageID && $parentViewable) $items->prepend($parent);
    
    // Line 523 from
    $numChildren = $id > 1 ? $page->numChildren : 0;
    // to
    $numChildren = $id != $config->rootPageID ? $page->numChildren : 0;
    
    // Line 551 from
    if($page->id > 1 && $page->numChildren) {
    // to
    if($page->id != $config->rootPageID && $page->numChildren) {
    
    //in your module
    public function ready() {
    $this->wire('config')->rootPageID = $this->branchRootParentId;
    // ...
    }

Working on a similar project, a kind of site parameterised site cloner. All in one PW install for maintenance commodity. Would love to see the outcome of this discussion :)

Hi @kixe - thanks for all your thoughts here. Hopefully you know that I have been away and not just ignoring your post!

The latest version has the getBranchRootParentId function hookable.

The reason I did this is because when a user is restricted to a branch of the page tree, there is no "Home" breadcrumb, so I added this to give them easy access back to the root of the pages they have access to. I am curious about the working solution you have though - maybe it takes care of what we both want?

I think that regardless of the interaction with this, module those "1" values shouldn't be hardcoded in the PW as you noted - maybe you could submit a PR to Ryan to fix those? As for the actual prepending of BranchRootParent to the Pagetree under PagesTab, do you mean here:

595d410885623_ScreenShot2017-07-05at12_41_40PM.png.c958f147dce322a2066dd0a1bfe6c4a7.png

Test One and Test Two and children of the BranchRootParent and as you note, the BranchRootParent itself is not shown. Not critical, but I agree it would be nicer if it was, but from some quick looking around I don't think it's going to be possible at the moment without manually prepending the BranchRootParent to the markup returned by  ProcessPageList::executeNavJSON - certainly possible, but not pretty.

Any thoughts on my comments?

I'd certainly like to help as much as possible for you on this, so just let me know.

Cheers,
Adrian

Great, Thanks!

Check out my fork to see the changes I made.
https://github.com/kixe/AdminRestrictBranch/tree/kixe

Everything is working pretty good together with the small changes in ProcessPageList::executeNavJSON()

Ryan is very busy and there are some other unsolved issues I am interested in. Furthermore there are many other places in the core where '1' is used instead of $config->rootPageID. I think it should be consistent but its not so easy to change this.

@adrian Thanks for this awesome module!

Until now, I didn't have a real use-case for this module, but for an upcoming project I think I might use it.

Is it possible to define more than one single branch tree? Let's say I have three areas (parents) I want to allow user x to see/edit, would I define this via "Branch parent to restrict access to"? Is that the way to go?

Unfortunately that's not possible with the way this module works.

There is lots of discussion floating around about why it's difficult to hide parts of the page tree - have a read starting here: https://processwire.com/talk/topic/1176-hiding-uneditable-pages-from-users/?do=findComment&comment=84916 - there are links to some different gists that might be helpful for you.

Great module @adrian.

For the Custom PHP Code option, can you make it also have access to the $pages variable (in addition to just the $user variable)?  I have a use case for it and it would be helpful.  I modified the module to include it and it worked fine for me.

Glad you like it 🙂

I don't see any reason not to. Would you mind submitting a PR? Please bump the version number as well so I can just accept and it's done.

Thanks!

I guess that is a way around needing to make $pages available. I just haven't got into using it yet - maybe I should?

I was not totally serious and it was more targeting @Jonathan Lahijani and meaning something like: Why not use the functions api when it is only one setting away and does not need any modifications to any module? $config->useFunctionsAPI = true, that's it.

22 minutes ago, adrian said:

Of course that's everybody's own decision, but I also started using it quite late and now I really like it. It makes things easier, shorter and better to read:

  public function executeTransactions() {
    $form = $this->modules->get('InputfieldForm');

    $f = $this->modules->get('InputfieldRockGrid');
    $f->name = 'transactions';
    $f->label = 'Overview of Transactions';
    $f->ajax = true;
    $form->add($f);

    return $form->render();
  }

I also prefer the array syntax now for adding fields:

  public function executeEfforts() {
    $form = modules('InputfieldForm');

    $form->add([
      'type' => 'RockGrid',
      'name' => 'efforts',
      'label' => 'Overview of Efforts',
      'ajax' => true,
    ]);

    return $form->render();
  }

To answer your question: If you've ever come across errors like "$pages/$modules/$users is not defined" or the like I'd suggest trying it out 😉 

Using VSCode + Intelephense I also get very nice code completion, so I don't see any reason not to use it. Only thing bothering me is when I am developing public modules I need to remember not to use the functions API as I can't assume everybody is using it.

Sorry it's taken so long to get to, but the latest version of the module now has a new config setting to optionally exclude pages outside the restricted branch from the search results of pages.

I tried the latest version of this wonderful module today: I activated the module's config setting "Restrict from search results". After that, I logged in with a user who is restricted to a certain branch and tried to find some pages outside the restricted branch.

I used the search box in the upper right corner of the PW admin and was surprised to see that results are found outside the restricted branch.

The quoted sentence above is related to a search by Lister, I guess?

@titanium - this used to work as expected - ie these pages could not be found via the search. I just took a look and it appears that relatively recent changes to this live search feature means that now other results are returned, but note that the links from these results go to view the returned pages, rather than allowing the user to edit them. So I think the main functionality has not been compromised.

Remember that this module is not designed to control view permissions, just editing.

Yeah, these view links are not helpful IMO. Related request: https://github.com/processwire/processwire-requests/issues/274

Edit: just noticed that you already thumbs-upped that. 🙂

IMPORTANT NOTICE!!!

Hi everyone. I just discovered something pretty important with this module.

If you are using the Role Name or Custom PHP Code option and matching a page name or path, you MUST be sure to check "No Access" for the "If no match, give all access or no access?" setting. If you don't do this, a site editor could change the name of their branch parent, which would result in no match and hence they could gain access to the entire page tree.

I am tempted to actually remove these two matching options to improve security - is anyone using them?

To make life easier, I have added a new "Role Specified Branch Parent" option which allows you to select a branch parent on a per role basis, rather than per user. I think in most cases this is the best option to use.

image.png.3d9d6575574a6ba68e4c8487707c25cf.png

Please be sure to check your settings and if you can please switch to the "Role specified" or "User specified" options in the new version.

Let me know if you have any questions or concerns.

Thanks,
Adrian

Hi

is it normal that if I add two different roles (that have different restricted branch) to a user, when I log in I can see only one branch?

Yep, because of the way this module works, it can only limit to one branch of the tree. This limit affects all places where the user could view and/or edit pages outside that branch. If you want to give access to multiple branches you'll need a different approach - this thread might be helpful:

      I often had the need for an overview of all used fields and their contents for a specific page/template while developing new websites without switching to the backend, so I made a small module which lists all the needed information in a readable manner (at least for me):
      Debug Page Fields
      https://github.com/robertweiss/ProcessDebugPageFields
      It adds two new properties to all pages:
      $page->debugFieldValues – returns an object with all (sub-)fields, their labels, fieldtypes and values $page->debugFieldTypes – returns an object with all fieldtypes and their corresponding fields // List all values of a pages $page->debugFieldValues // List a specific field $page->debugFieldValues->fieldname // List all used fieldtypes of a page $page->debugFieldTypes I recommend using it in combination with Tracy Debugger, Ray, Xdebug etc. as it returns an object and is only meant for developing/debugging uses. 
      For now, the fieldtype support includes mostly fieldtypes I use in my projects, but can easily be extended by adding a new FieldtypeFIELDNAME method to the module. I use it with five different client installations (all PW 3.0.*), but of course there might be some (or more) field configurations which are not covered correctly yet.
      Supported fieldtypes
      Button Checkbox Color Combo Datetime Email FieldsetPage * File FontIconPicker Functional Image ImageReference MapMarker Multiplier Mystique Options Page PageIDs PageTitle Radio Repeater * RepeaterMatrix * RockAwesome SeoMaestro Table Text Textarea Textareas Toggle URL * The fields with complete subfield-support also list their corresponding subfields.
      Installation
      Download the zip file at Github or clone the repo into your site/modules directory. If you downloaded the zip file, extract it in your sites/modules directory. In your admin, go to Modules > Refresh, then Modules > New, then click on the Install button for this module. As this is my first ›public‹ module, I hope I did not miss any important things to mention here.

      Wire Mail SMTP

      An extension to the (new) WireMail base class that uses SMTP-transport

      This module integrates EmailMessage, SMTP and SASL php-libraries from Manuel Lemos into ProcessWire. I use this continously evolved libraries for about 10 years now and there was never a reason or occasion not to do so. I use it nearly every day in my office for automated composing and sending personalized messages with attachments, requests for Disposition Notifications, etc. Also I have used it for sending personalized Bulkmails many times.

      The WireMailSmtp module extends the new email-related WireMail base class introduced in ProcessWire 2.4.1 (while this writing, the dev-branch only).
       
      Here are Ryans announcement.



      Current Version 0.6.0
      Changelog: https://github.com/horst-n/WireMailSmtp/blob/master/CHANGELOG.md
      get it from the Modules Directory Install and Configure

      Download the module into your site/modules/ directory and install it.

      In the config page you fill in settings for the SMTP server and optionaly the (default) sender, like email address, name and signature.
      You can test the smtp settings directly there. If it says "SUCCESS! SMTP settings appear to work correctly." you are ready to start using it in templates, modules or bootstrap scripts.


      Usage Examples
      The simplest way to use it:
      $numSent = wireMail($to, $from, $subject, $textBody); $numSent = wireMail($to, '', $subject, $textBody); // or with a default sender emailaddress on config page This will send a plain text message to each recipient.
       
      You may also use the object oriented style:
      $mail = wireMail(); // calling an empty wireMail() returns a wireMail object $mail->to($toEmail, $toName); $mail->from = $yourEmailaddress; // if you don't have set a default sender in config // or if you want to override that $mail->subject($subject); $mail->body($textBody); $numSent = $mail->send(); Or chained, like everywhere in ProcessWire:
      $mail = wireMail(); $numSent = $mail->to($toEmail)->subject($subject)->body($textBody)->send(); Additionaly to the basics there are more options available with WireMailSmtp. The main difference compared to the WireMail BaseClass is the sendSingle option. With it you can set only one To-Recipient but additional CC-Recipients.
      $mail = wireMail(); $mail->sendSingle(true)->to($toEmail, $toName)->cc(array('person1@example.com', 'person2@example.com', 'person3@example.com')); $numSent = $mail->subject($subject)->body($textBody)->send(); The same as function call with options array:
      $options = array( 'sendSingle' => true, 'cc' => array('person1@example.com', 'person2@example.com', 'person3@example.com') ); $numSent = wireMail($to, '', $subject, $textBody, $options); There are methods to your disposal to check if you have the right WireMail-Class and if the SMTP-settings are working:
      $mail = wireMail(); if($mail->className != 'WireMailSmtp') { // Uups, wrong WireMail-Class: do something to inform the user and quit echo "<p>Couldn't get the right WireMail-Module (WireMailSmtp). found: {$mail->className}</p>"; return; } if(!$mail->testConnection()) { // Connection not working: echo "<p>Couldn't connect to the SMTP server. Please check the {$mail->className} modules config settings!</p>"; return; }  
      A MORE ADVANCED DEBUG METHOD!
      You can add some debug code into a template file and call a page with it:
      $to = array('me@example.com'); $subject = 'Wiremail-SMTP Test ' . date('H:i:s') . ' äöü ÄÖÜ ß'; $mail = wireMail(); if($mail->className != 'WireMailSmtp') { echo "<p>Couldn't get the right WireMail-Module (WireMailSmtp). found: {$mail->className}</p>"; } else { $mail->from = '--INSERT YOUR SENDER ADDRESS HERE --'; // <--- !!!! $mail->to($to); $mail->subject($subject); $mail->sendSingle(true); $mail->body("Titel\n\ntext text TEXT text text\n"); $mail->bodyHTML("<h1>Titel</h1><p>text text <strong>TEXT</strong> text text</p>"); $dump = $mail->debugSend(1); } So, in short, instead of using $mail->send(), use $mail->debugSend(1) to get output on a frontend testpage.
      The output is PRE formatted and contains the areas: SETTINGS, RESULT, ERRORS and a complete debuglog of the server connection, like this one:
       
      Following are a ...


      List of all options and features


      testConnection () - returns true on success, false on failures


      sendSingle ( true | false ) - default is false

      sendBulk ( true | false ) - default is false, Set this to true if you have lots of recipients (50+)


      to ($recipients) - one emailaddress or array with multiple emailaddresses

      cc ($recipients) - only available with mode sendSingle, one emailaddress or array with multiple emailaddresses

      bcc ($recipients) - one emailaddress or array with multiple emailaddresses

       
      from = 'person@example.com' - emailaddress, can be set in module config (called Sender Emailaddress) but it can be overwritten here

      fromName = 'Name Surname' - optional, can be set in module config (called Sender Name) but it can be overwritten here


      priority (3) - 1 = Highest | 2 = High | 3 = Normal | 4 = Low | 5 = Lowest

      dispositionNotification () or notification () - request a Disposition Notification


      subject ($subject) - subject of the message

      body ($textBody) - use this one alone to create and send plainText emailmessages

      bodyHTML ($htmlBody) - use this to create a Multipart Alternative Emailmessage (containing a HTML-Part and a Plaintext-Part as fallback)

      addSignature ( true | false ) - the default-behave is selectable in config screen, this can be overridden here
      (only available if a signature is defined in the config screen)

      attachment ($filename, $alternativeBasename = "") - add attachment file, optionally alternative basename


      send () - send the message(s) and return number of successful sent messages


      debugSend(1) - returns and / or outputs a (pre formatted) dump that contains the areas: SETTINGS, RESULT, ERRORS and a complete debuglog of the server connection. (See above the example code under ADVANCED DEBUG METHOD for further instructions!)


      getResult () - returns a dump (array) with all recipients (to, cc, bcc) and settings you have selected with the message, the message subject and body, and lists of successfull addresses and failed addresses,


      logActivity ($logmessage) - you may log success if you want

      logError ($logmessage) - you may log warnings, too. - Errors are logged automaticaly
       
       
      useSentLog (true | false) - intended for usage with e.g. third party newsletter modules - tells the send() method to make usage of the sentLog-methods - the following three sentLog methods are hookable, e.g. if you don't want log into files you may provide your own storage, or add additional functionality here

      sentLogReset ()  - starts a new LogSession - Best usage would be interactively once when setting up a new Newsletter

      sentLogGet ()  - is called automaticly within the send() method - returns an array containing all previously used emailaddresses

      sentLogAdd ($emailaddress)  - is called automaticly within the send() method

      Food Allergens Module
      A simple List of Food Allergens
      My needs were to provide a simple list of food allergens for our clients with restaurant related activity.
      The idea was to simply output the list (to speed up the data entry) without leaving the food menu editing, eg. opening another page in new tab or window.
      This isn't a perfect solution, but it works fine for my needs and I decided to share the base idea.
      This could also be easily used to show little notes or short "vademecum", not only for the list of food allergens.
      ---
      Main features
      The basis
      All moves from a short editing of the module in this tutorial: How to create custom admin pages by @bernhard
      First of all it creates an empty admin page, with a dedicated permission to let safe-user to see it (this permission has to be created as a new ones, manually or by the module).
      Once the page is created, I have hooked its behaviour into the ready.php, to show the content (basically a list).
      A step further
      With the tips of  @bernhard, @Soma (and many others), see here , the magic happens. 
      The new page will be shown as a panel, so editors will not abandon their data entry to have a quick view to the list.
      A little further
      Why scroll to the top of the page to click a link?
      The next step was to create a sticky button only in the food menu pages.
      Again with a @bernhard tip I moved into the customization of this simple module and the related hook.

      How to use this module
      After installed, it creates the page /admin/page/allergens/ and the module is to be setted up. The first field is a CKEditor with multi-language. This is the place where to write the informations that will be shown into the page. The next field is a simply text-area where to place a bit of JS that will be appended to the markup of the text (omit the 'script' tags). I also putted a checkbox with a silly statement: this to think at least twice on the safety of the written JS. Now comes the first way to display the link to the page
      Field Note with Link. Enable and save it. The module will display a new row with 4 selects (1 standard and 3 ASM):
      View mode (to show the page as Panel or as Modal PopUp); Templates to select: select one or more and save before proceed, so the  asm-select of the pages will be populated showing all the pages of the selected templates. Pages to select: also here select at least one and save before proceed to populate the asm-select for fields only with the ones that belong to the selected pages. Select the fields where to place the note and save again. That's all: now you will find into the notes of the selected fields the link "See the List of Allergens".
      At the same way, the option for the sticky button, but with a plus
      The field select is obviously unnecessary, but you could play with the last row: the inline styles to fix your sticky button where you like. Here you could set the sticky position of the <div> and the absolute ones of the <a>.

      Video Explanation
      In these screencasts you could see a custom JS that show a "copy" button near a "hanna-code" call.
      This because I've set a specific one for each allergen to show up a tooltip in the front end.

      Last but not the least
      Actually it works fine for my needs, even if it's much improvable: I'm working on the permissions creation, the uninstall section, a separate configs and defaults and how to include the hook into the module leaving free the ready.php. According to a simpler uninstall. Also I would make the link text as a dynamic text field, so it will be more flexible.
      I always learn a lot here, so I would share my code for whom it could be interested.
      I removed the hanna code references, but I provide you the html list of the allergens, English and Italian too, so you can paste them into the "source" of the CKEditor field to have a ready to use module.
      Obviously you are free to modify the code as per your needs.
      Please, keep in mind that I'm not a pro coder and I beg your pardon for my verbosity (speaking and coding). 😉
      I hope be helpful or for inspiration.

      This module is sort of an upgrade to my earlier ImageToMarkdown module, and might be useful to anyone working with Markdown in ProcessWire.
      Copy Markdown
      Adds icons to images and files that allow you to copy a Markdown string to the clipboard. When you click the icon a message at the top left of the screen notifies you that the copying has occurred.
      Screencast

      Note: in the screencast an EasyMDE inputfield is used to preview the Markdown. It's not required to use EasyMDE - an ordinary textarea field could be used.
      Usage: Images
      When you hover on an item in an Images field an asterisk icon appears on the thumbnail. Click the icon to copy an image Markdown string to clipboard. If the "Description" field is populated it is used as the alt text.
      You can also open the "Variations" modal for an image and click the asterisk icon to copy an image Markdown string for an individual variation.
      Usage: Files
      When you hover on an item in a Files field an asterisk icon appears next to the filename. Click the icon to copy a link Markdown string to the clipboard. If the "Description" field is populated it is used as the link text, otherwise the filename is used.

      I've realized that I've been jumping back and forth between the PW API docs and the source code for site modules far too much. The idea to hold all necessary documentation locally in one place has occurred to me before, but getting PHPDocumentor et al set up and running reliably (and producing readable output) as always been too much of a hassle. Today I was asked how I find the right hooks and their arguments, and that inspired me to finally get my backside down on the chair and whip something up, namely the
      Module Api Doc Viewer
      ProcessModuleApiDoc
      It lets you browse the inline documentation and public (optionally also protected) class/method/property information for all modules, core classes and template files in the ProcessWire instance. The documentation is generated on the fly, so you don't have to remember to update your docs whenever you update a module.
      The module is quite fresh, so expect some bugs there. Behind the scenes it uses PHP-Parser together with a custom class that extracts the information I needed, and the core TextformatterMarkdownExtra module for rendering the description part in the phpdoc style comments.
      This is not a replacement / competitor to the API Viewer included in the commercial ProDevTools package. There is quite some information included in the inline documentation that my module can't (and won't) parse, but which makes up parts of the official ProcessWire API docs.
      This, instead, is a kind of Swiss army knife to view PHPDoc style information and get a quick class or function reference.
      If you feel daring and want to give it a spin, or if you just want to read a bit more, visit the module's GitHub repository.
      This is the overview page under "Setup" -> "Module API Docs":

      And this is what the documentation for an individual class looks like:

      The core module documentation can of course be found online, but it didn't make sense not to include them.
      Let me know what you think!
